BACKGROUND 1. Field

The invention relates generally to an apparatus for holding a decorative cover, a kit and a system including the same, a headboard apparatus comprising a substantially thermoplastic body, a furniture apparatus comprising diatomaceous earth, legume extracts, or both, and use of one of the apparatuses, kits, or systems to control a population of animals.

2. Related Art

Many bedrooms in homes and hotels, for example, include headboards, which may be attached to a head of a bed, or which may be attached to a wall proximate the head of the bed. Many conventional headboards include a decorative cover upholstered to a wooden frame. However, wood is disadvantageously difficult to clean, and upholstered decorative covers may be difficult or impossible to replace. Generally, once an upholstered cover is removed from a frame, the cover will be significantly damaged where it was attached, and either not reusable or reusable only on a smaller frame. Therefore, if such a headboard becomes infested with Cimex lectularius (also known as “bedbugs”) or if there is a desire to change the decorative cover for a new colour scheme, for example, then generally such conventional headboards must be discarded and replaced. Discarding and replacing headboards is wasteful and environmentally damaging, and may be very expensive or cost-prohibitive for large institutions such as hotels, for example. Further, in some institutions such as hotels for example, closing large parts or all of the hotel for bedbug or other pest removal can result in significant loss of revenue.

There have been attempts to attach decorative covers by techniques other than conventional upholstery. For example, U.S. Pat. No. 2,508,506 to Fridolph (“Fridolph”) discloses receiving fastener heads, which are around a perimeter of a decorative panel, in respective recesses on a frame, and then in respective slots adjacent the recesses. The slots hold the fastener heads, and thus the decorative panel, to the frame. However, such a technique attaches the decorative panel only at discrete locations of the fastener heads, thereby leaving unsightly gaps along the perimeter of the decorative panel between the discrete locations where the decorative panel is attached. Further, to position the fastener heads in the slots, the fastener heads must be received in the respective recesses and then slid from the respective recesses into the adjacent slots. Disadvantageously, sliding the fastener heads from respective recesses into respective slots may require stretching or deforming the decorative panel. Further, the fastener heads may have to be spaced a minimum distance from the decorative panel to permit such sliding, and because of such spacing the fastener heads may not hold the decorative panel close to the frame. The decorative panel may therefore not be tightly held against the frame, disadvantageously giving the decorative panel a loose or saggy appearance. It is believed that at least because of such disadvantages, a headboard as disclosed by Fridolph would not be commercially viable and is unlikely to have been produced commercially.

Also, U.S. Pat. No. 5,195,195 to Murray (“Murray”) discloses covering a front side of a headboard with fabric, and positioning tubing in a groove in a back side of the headboard to hold the fabric in the groove under the tubing. However, such a technique requires carefully positioning the fabric on the headboard, and maintaining the fabric in position while the tubing is positioned in the groove. Simultaneously holding the fabric and positioning the tubing is disadvantageously cumbersome and time-consuming. Again, it is believed that at least because of such disadvantages, a headboard as disclosed by Murray would not be commercially viable and is unlikely to have been produced commercially.

Some known methods of controlling bedbug and other pest populations involve using certain pesticides, but some pesticides may be harmful to humans and to other life. Other known methods of controlling bedbug populations include applying diatomaceous earth, but known methods of applying diatomaceous earth can be cumbersome. For example, known methods of applying diatomaceous earth may undesirably require handling the diatomaceous earth. Further, known methods may be sufficiently complex so as to require professional involvement, which may undesirably add to cost and delay of bedbug treatment.

DETAILED DESCRIPTION

Referring to FIG. 1, an illustrative room includes a floor 86, a wall 88, and an illustrative furniture system shown generally at 90 and including a nightstand 92, a dresser 94, a bed 96, a mattress 98, and a headboard system 100.

Referring to FIG. 2, the headboard system 100 includes a decorative cover 102, padding 104, a body 106, and a wall-mountable cleat 108. The decorative cover 102 in the embodiment shown includes a generally rectangular portion 110 having an outer surface 112. The outer surface 112 may include any decorative colours, ornamentation, or pattern, for example. The decorative cover 102 also includes lateral portions 114, 116, 118, and 120 extending generally from a perimeter of the generally rectangular portion 110 and generally perpendicular to the generally rectangular portion 110. The generally rectangular portion 110 and the lateral portions 114, 116, 118, and 120 may be made from any commonly available fabric and may be stitched together, for example.

Referring to FIG. 3, the lateral portions 114, 116, 118, and 120 have respective inner surfaces 122, 124, 126 and 128 facing the generally rectangular portion 110. The lateral portions 114, 116, 118, and 120 also have respective outer edges 130, 132, 134, and 136. The decorative cover 102 also has a connector 138 on the inner surfaces 122, 124, 126, and 128 proximate the outer edges 130, 132, 134, and 136. In the embodiment shown, the connector 138 is a so-called “loop side” of a hook-and-loop connector, such as the hook-and-loop connector commonly known as VELCRO™ for example.

Referring back to FIG. 2, the padding 104 in the embodiment shown includes a generally rectangular body made from one or more of many commonly available foam materials. In alternative embodiments, the padding 104 may include an air bladder or feather padding, for example. Therefore the padding 104 in some embodiments may be selected to avoid undesired allergens, for example. The padding 104 may include a fire-retardant substance as may be required by law. Further, the padding 104 is sized to be received in a recess shown generally at 140 in FIG. 3 and defined by the generally rectangular portion 110 and the lateral portions 114, 116, 118, and 120 of the decorative cover 102.

Referring to FIGS. 2, 4, and 5, the body 106 has a front side shown generally at 142 and having a front surface 144 having a perimeter 146. The body 106 also has a rear side shown generally at 148 opposite the front side 142 and having a rear surface 150. The body 106 also has an outwardly facing lateral surface 152 between the front surface 144 and the rear surface 150. Further, a connector 154 is on the body 106 continuously adjacent at least a portion of the perimeter 146 of the front surface 144. In the embodiment shown, the connector 154 is a so-called “hook side” of a hook-and-loop connector, such as the hook-loop-connector commonly known as VELCRO™ for example.

Therefore, the connector 154 (which may be referred to as “a first connector” or more generally as “a holder”) on the body 106 is detachably connectable to the connector 138 (which may be referred to as “a second connector”) on the decorative cover 102. In the embodiment shown, the connector 138 on the decorative cover 102 and the connector 154 on the body 106 are so-called “loop side” and “hook side” sides respectively of a hook-and-loop connector, and thus the connector 154 on the body 106 is complementary to the connector 138 on the decorative cover 102.

In alternative embodiments, the decorative cover 102 may include a “hook side” of a hook-and-loop connector and the body 106 may include a “loop side” of the hook-and-loop connector, for example. Also, although the connector 154 is on the lateral surface 152 of the body 106 in the embodiment shown, the connector 154 may be on the front surface 144 or on the rear surface 150, for example, in alternative embodiments. Thus, “adjacent the perimeter 146” in this context does not require the connector 154 to adjoin or be precisely on the perimeter 146, but rather it includes embodiments where the connector 154 is close enough to the perimeter 146 that when the connector 154 is connected to the connector 138, the decorative cover 102 appears to cover at least a portion of the front surface 144 surrounded by the perimeter 146 such that the headboard system 100 generally functions as a headboard or more generally as a decorative panel.

Further, in the embodiment shown, the connector 154 extends adjacent the entire perimeter 146 of the front surface 144. However, in alternative embodiments, the connector 154 may extend adjacent substantially the entire perimeter 146 of the front surface 144, or the connector 154 may extend adjacent at least a majority of the perimeter 146 of the front surface 144. The connector 154 may be considered to extend adjacent “substantially” the entire perimeter 146 of the front surface 144 if the connector 154 extends adjacent a sufficient portion of the perimeter 146 such that the connector 154 is connectable to the connector 138 on the decorative cover 102 such that the decorative cover 102 appears to be connected continuously on the body 106.

Still referring to FIGS. 2 and 4, the body 106 defines a projection 156 having the lateral surface 152 and an inward-facing surface 158. In the embodiment shown, the front surface 144 of the body 106 includes the inward-facing surface 158 of the projection 156, and a generally flat planar portion 160. Further, the inward-facing surface 158 is between the generally flat planar portion 160 and the lateral surface 152 of the body 106. The inward-facing surface 158 and the generally flat planar portion 160 define a recess shown generally at 162 for receiving the padding 104 between the body 106 and the decorative cover 102.

Referring to FIGS. 2, 4, and 5, the body 106 defines through-openings shown generally at 164, 166, 168, 170, 172, 174, 176, 178, and 180 in the generally flat planar portion 160 of the front surface 144 and extending between the front surface 144 and the rear surface 150. As shown in FIG. 5, on the rear side 148, the body 106 defines respective cleats proximate the through-openings 164, 166, 168, 170, 172, 174, 176, 178, and 180. For example, referring to FIG. 6, the body 106 defines a cleat 182 on the rear side 148 and proximate the through-opening 172. The cleat 182 includes a relatively wide portion shown generally at 184, and a relatively narrow portion shown generally at 186 between the relatively wide portion 184 and the rear surface 150. The cleat 182 thus permits a thread or string that is passed through the through-opening 172 to be tied around the relatively narrow portion 186 and held in position by the relatively wide portion 184.

Referring to FIGS. 2, 5, and 6, the padding 104 may be received in the recess 162 of the body 106, and also in the recess 140 (also shown in FIG. 3) of the decorative cover 102. For example, using a needle (not shown), thread or string may be passed through one or more of the through-openings 164, 166, 168, 170, 172, 174, 176, 178, and 180, through the padding 104 and the decorative cover 102, through a button (not shown), and back through the decorative cover 102, the padding 104, and the through-openings of the body 106. The thread or string may then be fastened to a respective cleat, such as the cleat 182 shown in FIG. 6, for example. Therefore, the through-openings and respective cleats permit respective buttons (not shown) to be pulled against the decorative cover 102 and the padding 104 to compress regions of the padding 104 proximate the buttons to impart a textured appearance to the outer surface 112 of the decorative cover 102. In that example, the buttons and thread or string function as fasteners received through the through-openings, through the padding 104, and through the decorative cover 102 to compress the padding 104 in respective regions surrounding the respective fasteners.

Referring to FIGS. 2, 4, and 5, the body 106 defines additional through-openings 188, 190, 192, 194, 196, 198, and 200 extending between the front surface 144 and the rear surface 150. Such additional through-openings in some embodiments may reduce weight and production cost of the body 106. In alternative embodiments, the through-openings 188, 190, 192, 194, 196, 198, and 200 may be omitted or may have different shapes, or may alternatively be closed with a thin film of thermoplastic material (not shown). Such a thin film of thermoplastic material in some embodiments may protect padding (such as the padding 104 shown in FIG. 2, for example) by preventing such padding from passing through the through-openings 188, 190, 192, 194, 196, 198, and 200, or by preventing objects that may damage the padding from passing through the through-openings 188, 190, 192, 194, 196, 198, and 200.

Referring to FIG. 5, on the rear side 148, the body 106 in the embodiment shown also defines a plurality of structural ribs, such as illustrative structural ribs 202 and 204 to impart additional strength to the body 106.

Referring to FIG. 7, in the embodiment shown, the projection 156 extends at an oblique angle 206 from the generally flat planar portion 160 of the body 106, and the body 106 also defines a projection 208 on the rear side 148 extending generally perpendicularly from the generally flat planar portion 160. In the embodiment shown, the connector 154 is on the projection 208, and the lateral surface 152 is on the projection 156 and 208. However, in alternative embodiments, the connector 154 may be on the projection 156 or, as indicated above, on the front surface 144 or on the rear surface 150.

Referring to FIG. 8, the body 106 is stackable against an adjacent similar body 210 on the front side 142 of the body 106, and against an adjacent similar body 212 on the rear side 148 of the body 106. In the embodiment shown, the adjacent similar body 210 has a lateral surface 214 that is substantially the same as the lateral surface 152 of the body 106, and the lateral surfaces 152 and 214 are positioned such that a portion of the lateral surface 214 of the adjacent similar body 210 contacts a portion of the inward-facing surface 158 of the body 106 when the adjacent similar body 210 is received in the recess 162 of the body 106 and stacked against the front side 142. Further, the adjacent similar body 212 has an inward-facing surface 216 that is substantially the same as the inward-facing surface 158 of the body 106, and at least a portion of the lateral surface 152 of the body 106 contacts at least a portion of the inward-facing surface 216 of the adjacent similar body 212 when the adjacent similar body 212 is stacked against the rear side 148 of the body 106.

Referring back to FIG. 5, the body 106 defines additional projections 218, 220, 222, 224, 226, 228, 230, 232, and 234 on the rear side 148. Referring back to FIG. 7, the projection 218 defines a cavity 236 and an opening shown generally at 238 on the rear side 148 of the body 106 and in communication with the cavity 236. The body 106 also defines an opening 240 extending between the front surface 144 of the body 106 and the cavity 236. Referring back to FIG. 5, the projections 220, 222, 224, 226, 228, 230, 232, and 234 are substantially the same as the projection 218 and define respective openings shown generally at 242, 244, 246, 248, 250, 252, 254, and 256 that are substantially the same as the opening 238. In general, the openings 238, 242, 244, 246, 248, 250, 252, 254, and 256 face inwardly from respective cavities in the respective projections.

Referring back to FIG. 8, the adjacent similar bodies 210 and 212 have respective projections 258 and 260 that are substantially the same as the projection 218. When the adjacent similar body 210 is stacked against the front side 142 of the body 106, the projection 258 of the adjacent similar body 210 contacts the front surface 144 of the body 106, and when the adjacent similar body 212 is stacked against the rear side 148 of the body 106, the projection 218 contacts a front surface 262 of the adjacent similar body 212 that is substantially the same as the front surface 144 of the body 106. Referring to FIGS. 5 and 8, the projections 218, 220, 222, 224, 226, 228, 230, 232, 234, 258, and 260 in some embodiments may thus increase contact between stacked bodies such as the stacked bodies 106, 210, and 212 as illustrated in FIG. 8, for example, and such embodiments may thus have added stability in a stacked system of bodies, such as the stacked system shown in FIG. 8 for example.

Referring back to FIG. 5, on the rear side 148, the body 106 also has a plurality of clips, such as illustrative clips 264 and 266, proximate the projection 208. Referring back to FIG. 7, the clip 266 includes a deformable curled portion 268 for detachably receiving a light source (not shown) such as a light string of light-emitting diodes (“LEDs”), for example. Thus, referring back to FIG. 5, the plurality of clips shown proximate the projection 208 function as a light source connector to connect such a light string to the body 106 substantially around a perimeter of the rear surface 150 of the body 106. Alternative connectors for the light source may include tape, for example.

Still referring to FIG. 5, electrical switches 270 and 272 are positioned on the projection 208 of the body 106 through the lateral surface 152. Referring to FIG. 9, the electrical switch 270 is illustrated, and the electrical switch 272 is substantially the same. The electrical switches 270 and 272 in the embodiment shown are three-way switches, and thus both can be connected to a light source (not shown) such that either electrical switch 270 or 272 can turn the light source on or off. The body 106 may also have a voltage converter (not shown) to supply an appropriate voltage to the light string of LEDs, for example.

Referring back to FIG. 7, the projection 208 in the embodiment shown includes a translucent portion 274 for transmitting light from a light source (not shown) held in the clips such as the clips 264 and 266. Alternative embodiments may include a detachable translucent cover, or alternatively the translucent portion 274 may be omitted to leave a gap in the body 106 in place of the translucent portion 274, through which light may pass. Although in the embodiment shown the only translucent portion is the translucent portion 274, in alternative embodiments other portions or substantially all of the body 106 may be translucent, in which embodiments the body 106 may be formed of a single type of thermoplastic material.

Referring back to FIG. 2, the cleat 108 defines a plurality of through-openings, such as illustrative through-openings 276 and 278, for receiving fasteners (not shown) to mount the cleat 108 on a wall (such as the wall 88 shown in FIG. 1). Such through-openings are elongate in the embodiment shown to permit fasteners (not shown) to be attached to studs (not shown) in the wall, and to permit the cleat 108 to be slidable relative to such fasteners, which in some embodiments may enable the cleat 108 to be mounted on a wall in a position that may not be unduly restricted by positions of such studs. The cleat 108 also includes projections 280, 282, and 284 having respective upper edges 286, 288, and 290. The projections 280, 282, and 284 in the embodiment shown are spaced apart by a common spacing distance, and referring back to FIG. 5, the openings 238, 242, and 244, the openings 246, 248, and 250, and the openings 252, 254, and 256 are spaced apart by the same spacing distance. Therefore, in one embodiment, the openings 238, 242, and 244 may receive the projections 284, 282, and 280 respectively to mount the body 106 on the wall (such as the wall 88 shown in FIG. 1) to which the cleat 108 may be mounted. For example, FIG. 10 illustrates the projections 280 and 282 received in the openings 244 and 242 respectively.

In some embodiments, projections such as the projections 280, 282, and 284 may function as latches that cooperate with inner surfaces of projections such as the projections 222, 220, and 218 such that the projections 280, 282, and 284 are releasably held within the projections 222, 220, and 218 respectively, and such that the projections 280, 282, and 284 may be temporarily deformed to release the body 106 from the cleat 108. The projections 280, 282, and 284 in the embodiment shown are accessible from the front side 142 of the body 106, and may thus function as release switches to release the body 106 from the cleat 108, and in some embodiments may hold the body 106 on the cleat 108 such that the body 106 can only be released from the cleat 108 when the decorative cover 102 and padding 104 have been removed. Such releasable connection in such embodiments may further secure the body 106, padding 104, and decorative cover 102 to a wall (such as the wall 88 shown in FIG. 1).

Referring to FIGS. 2 and 5, respective spaced apart edges of the projections 218, 220, and 222 thus function as a connector on the body 106 for mounting the body 106 on a wall (such as the wall 88 shown in FIG. 1). Further, the plurality of spaced apart upper edges 286, 288, and 290 of the projections 280, 282, and 284 respectively thus function as a connector complementary to such a connector on the body 106.

Still referring to FIGS. 2 and 5, the projections 280, 282, and 284 of the cleat 108 may alternatively be received in the openings 246, 248, and 250 respectively of the projections 224, 226, and 228 respectively. The projections 224, 226, and 228 include edges that are complementary to the upper edges 286, 288, and 290 respectively of the projections 280, 282, and 284 respectively, and such edges in the projections 224, 226, and 228 are generally perpendicular, and more generally non-parallel, to substantially similar edges in the projections 218, 220, and 222. The body 106 may thus be hung in a manner perpendicular to the manner shown in FIG. 10. Further, the projections 284, 282, and 280 of the cleat 108 may also be received in the openings 252, 254, and 256 respectively of the projections 230, 232, and 234 respectively, again mounting the body 106 perpendicular to the manner shown in FIG. 10. The plurality of respective spaced apart edges of the projections 224, 226, and 228 thus also function as another connector for mounting the body 106 on a wall (such as the wall 88 shown in FIG. 1), and the plurality of respective spaced apart edges of the projections 230, 232, and 234 also function as a connector for mounting the apparatus body 106 on a wall.

Referring back to FIG. 5, the body 106 in the embodiment shown defines, on the rear side 148, a storage compartment 292 for storing objects. For example, it may be desirable to store small but valuable objects invisibly within the headboard system 100 (shown in FIG. 2). In some embodiments, the storage compartment 292 may hold one or more of buttons, a needle, and thread to impart a textured appearance to the outer surface 112 of the decorative cover 102 as described above, for example. In the embodiment shown, the storage compartment 292 is open at an opening shown generally at 294 on a top side of the storage compartment 292. However, in alternative embodiments, the storage compartment 292 may include a removable cover, for example.

Referring back to FIG. 2, in the embodiment shown, the body 106 has an inclination measuring device 296 on the front side 142. The cleat 108 also includes an inclination measuring device 298. The inclination measuring devices 296 and 298 in the embodiment shown are removable bubble levels, which in some embodiments may reveal an inclination of the body 106 and the cleat 108 respectively relative to gravitational force. Such inclination information in such embodiments may assist in positioning the cleat 108 and the body 106 level in a room, for example.

Referring to FIG. 11, the headboard system 100 is shown assembled such that the padding 104 is received in the recess 162 of the body 106 and in the recess 140 of the decorative cover 102. The lateral portions 114, 116, 118, and 120 are positioned over the lateral surface 152 of the body 106 and the connector 154 on the decorative cover 102 is detachably connected to the connector 138 on the body 106, leaving the outer surface 112 exposed to decorate a room, for example. The body 106 in the embodiment shown thus functions as an apparatus for holding the decorative cover 102, and may thus function as a headboard for a bed in some embodiments.

The hook-and-loop connectors 138 and 154 in the embodiment shown may avoid time and expense that would be involved with upholstering the decorative cover 102 to the body 106. If there is a desire to change the decorative cover 102, for example to update the outer surface 112 to reflect a new colour scheme, then the decorative cover 102 may be replaced simply by detaching the hook-and-loop connectors 138 and 154 and reattaching a connector 138 of a new decorative cover 102 to the connector 154 of the body 106.

In the embodiment shown, the body 106 and the cleat 108 are substantially thermoplastic and may be formed from high-density polyethylene or polypropylene, for example, although other thermoplastic materials, such as carbon plastic for example, may alternatively be used. The body 106 and the cleat 108 may include materials that are not thermoplastic, such as the electrical switches 270 and 272 and the inclination measuring devices 296 and 298 for example, but still be “substantially” thermoplastic. In general, a “substantially” thermoplastic body may include principal structural elements that may be formed in a mold, which may permit relatively inexpensive production of a large number of such bodies, but such a “substantially” thermoplastic body may also include elements that are not thermoplastic, such as elements of the electrical switches 270 and 272 and elements of the inclination measuring devices 296 and 298 for example. The body 106 and the cleat 108 may be made from any commonly available thermoplastic material, which may include an additive such as an additive known as ECOPURE™ available from Bio-Tec Environmental, LLC of Albuquerque, N. Mex., for example. Alternative embodiments may include other materials, which may not be thermoplastic in some embodiments.

If the headboard system 100 becomes infested with bedbugs, for example, then the decorative cover 102 and the padding 104 may be removed from the body 106 and either discarded or cleaned and replaced. For example, to kill bedbugs, the decorative cover 102 may be laundered and the padding 104 may be simply left in storage for a sufficient period of time, among other possibilities. Further, the body 106 is substantially thermoplastic and thus may be readily cleaned, and a new or cleaned decorative cover 102 and new or cleaned padding 104 may be installed on the cleaned body 106, which in some embodiments may avoid waste, expense, and environmental damage of replacing entire headboards. Such reduced waste and expense may be particularly advantageous in large institutions such as hotels for example, where responding to bedbug infestations can be very costly. Further, if it is desired to change an appearance of the decorative cover 102 or to change the padding 104, for example, then only those components need be replaced, which may reduce costs to change décor or padding material in one or more rooms or in an entire hotel, for example.

More generally, the headboard system 100 may be more hygienic than known headboards, such as upholstered headboards for example, because the substantially thermoplastic body 106 in some embodiments may be sanitized or otherwise cleaned, and the decorative cover 102 and the padding 104 may be removed, cleaned, and replaced, whereas similar components in upholstered headboards, for example, generally cannot be reused and must be discarded once removed. Therefore, some embodiments of a substantially thermoplastic body having any holder for holding a decorative cover in a headboard may be advantageous over many known headboards.

Further, one or both of the body 106 and the cleat 108 may include diatomaceous earth incorporated therein. In one embodiment, diatomaceous earth is incorporated in the body 106 by adding the diatomaceous earth to the thermoplastic material of the body 106 when the thermoplastic material is in a liquid phase before the thermoplastic material is injected into a mold. In one embodiment, about 30% by weight of the body 106 is diatomaceous earth. Further, additional diatomaceous earth may be adhered to the outwardly facing lateral surface 152 or other surfaces of the body 106. In some experiments, it has been found that bodies including diatomaceous earth in that manner effectively kill bedbugs that are in proximity to such a body. In one such experiment, such a body continued to cause death to bedbugs for at least one year after the body was manufactured. Therefore, such materials may further prevent or reduce bedbug infestations, which can be very costly in large institutions such as hotels, for example.

The diatomaceous earth in some embodiments may include CELATOM™ MN-51, which is available from EP Minerals, LLC of 9785 Gateway Drive, Suite 1000, Reno, Nev., United States of America, and which may be heat-treated or flash dried at about 900° F. (about 480° C.) or at other temperatures, for example. In one embodiment, flash drying diatomaceous earth involves heating the diatomaceous earth at about 900° F. (about 480° C.) for about 15 seconds. It is believed that such heat treatment or flash drying may change the characteristics of the diatomaceous earth to be more abrasive and thus more damaging to animal exoskeletons, or more particularly to bedbug exoskeletons, and that such heat treatment or flash drying may also dry out the diatomaceous earth, thereby making the diatomaceous earth more absorbent to dehydrate and kill an animal such as bedbug and potentially more effective in various embodiments including the various embodiments described herein.

The diatomaceous earth known as CELATOM™ MN-51 may be particularly effective in some embodiments, and such diatomaceous earth is believed to have the following properties.

In an alternative embodiment, the diatomaceous earth may include diatomaceous earth known as CELATOM™ MN-53, which is also available from EP Minerals, LLC of 9785 Gateway Drive, Suite 1000, Reno, Nev., United States of America. The diatomaceous earth known as CELATOM™ MN-53 is believed to have the following properties.

In one experiment on Jun. 23, 2011, small plastic Petri dishes available from Gelman Sciences™, each about 5.0 centimeters (“cm”) or about 2.0 inches in diameter, were used in bioassays. A small opening of about 1.5 cm (or about 0.6 inches) in diameter was cut in the lid and closed with a piece of gauze to allow air for bedbug breathing. The Petri dishes were lined with a filter paper about 4.25 cm (or about 1.7 inches) in diameter. Diatomaceous earth was weighed and spread uniformly over the filter paper with forceps. Ten adult field-collected bedbugs were introduced in each of the Petri dishes, and the lids were placed over them to prevent their escape. Petri dishes were transferred in a plastic box lined with paper towels sprayed with water to maintain humidity in the box. Experiments were conducted at room temperature, and mortality was noted 24, 48, 72, and 96 hours after the bedbugs were introduced into of the Petri dishes. Four concentrations, between about 0.5 and about 2.0 milligrams (“mg”), were used to calculate a lowest lethal concentration sufficient to kill 50% of the bedbugs (“LC₅₀”) of each product. There was a single replication of 10 bedbugs each.

Tables 3 and 4 below show mortality data from the Jun. 23, 2011 experiment, where L refers to a number of bedbugs still living after a corresponding time given in the tables, and D refers to a number that died after the time given.

TABLE 3 Toxicity of adult bedbugs to CELATOM ™ MN-51 Amount of CELATOM ™ MN-51 Time 2.0 mg 1.0 mg 0.8 mg 0.5 mg (hours) L D L D L D L D 48 0 10 3 7 4 6 5 5 72 0 3 0 4 0 5

All of the bedbugs died in CELATOM™ MN-51 diatomaceous earth after 48 hours. Therefore, LC₅₀ for CELATOM™ MN-51 was calculated for 48 hours only, and LC₅₀ after 48 hours for CELATOM™ MN-51 was calculated as 0.7 mg. The data after 48 hours for CELATOM™ MN-53 were not good for calculation, and therefore LC₅₀ for CELATOM™ MN-53 was calculated after 96 hours as 0.8 mg (0.552-1.052).

The relatively low LC₅₀ for CELATOM™ MN-51 suggests that CELATOM™ MN-51 may be more toxic for bedbugs than CELATOM™ MN-53, and that CELATOM™ MN-51 may be particularly effective for the control of insects, or more particularly for the control of bedbugs.

In another experiment on Feb. 1, 2012, six Petri dishes (each about 5.0 cm or about 2.0 inches in diameter) were sprayed with an aerosol including CELATOM™ MN-51, and a thin coating of the CELATOM™ MN-51 remained after drying; those six Petri dishes were used for an experimental group. An additional six Petri dishes (each 5.0 cm or about 2.0 inches in diameter) did not receive the aerosol or the diatomaceous earth; those six Petri dishes were used for a control group. Five bedbugs were introduced into each of the 12 Petri dishes, and lids were applied to prevent the bedbugs from escaping. Mortality was assessed 3, 15, 18, and 24 hours after the bedbugs were introduced into the Petri dishes, and there was no mortality in the control group. Mortality in the experimental group is shown in Table 5 below.

TABLE 5 Number of bedbugs dead from aerosol including CELATOM ™ MN-51. Petri Number dish dead Number dead Number dead Number dead number after 3 hours after 15 hours after 18 hours after 24 hours 1 0 5 5 5 2 0 2 3 5 3 0 5 5 5 4 0 4 5 5 5 0 5 5 5 6 0 3 3 5 Total 0 24 26 30

Thus, in the Feb. 1, 2012 experiment, all of the bedbugs exposed to the aerosol including CELATOM™ MN-51 died within 24 hours, whereas none of the control group bedbugs died within 24 hours.

Another experiment on Feb. 12, 2012 involved plastic RUBBERMAID™ translucent boxes (about 73.6 cm×about 45.7 cm×about 33.7 cm, or about 29 inches×about 18 inches×about 13.3 inches), more particularly two such boxes as experimental boxes and two such boxes as control boxes. A section about 20 cm (or about 7.9 inches) wide in the center of each of the experimental boxes was sprayed with the aerosol including CELATOM™ MN-51 and allowed to dry. A piece of a field-collected sheet (about 50 cm×about 24 cm, or about 19.7 inches×about 7.9 inches) was lined on one side of each of the boxes and used as a stimulant. The sheet was collected from a home infested with bedbugs, and had eggs and many freshly fed bedbugs, but the bedbugs were collected from the sheet before placing pieces of the sheet into the boxes. Sides of the boxes opposite the pieces of the field-collected sheet were lined with a clean and new piece of cloth. Fifty adult bedbugs were introduced into each box on the clean cloth, and then the box was closed with a lid. The control boxes were similar to the experimental boxes but did not include the aerosol.

In all four of the boxes, the bedbugs moved from the sides of the boxes having the clean cloths to the sides of the boxes having the pieces of the field-collected sheet. There was no mortality in the control boxes after 48 hours, but after 24 hours, one of the experimental boxes had mortality of 43 of the 50 bedbugs, and the other of the experimental boxes had mortality of 45 of the 50 bedbugs. All of the bedbugs in the experimental boxes died after 48 hours. The bedbugs were found dead lying on their backs and dusted with the product from the aerosol. Therefore, it is believed that even a brief exposure as bedbugs cross an area treated with CELATOM™ MN-51 is sufficient to cause high mortality in the bedbugs.

It is also believed that when one bedbug contacts diatomaceous earth, that bedbug may spread the diatomaceous earth to other bedbugs, and therefore causing one bedbug to contact diatomaceous earth may cause death of several bedbugs. For example, in one experiment, a bedbug was allowed to contact diatomaceous earth and a fluorescent dye directly, and that bedbug was allowed to contact several other bedbugs that had not been allowed to contact the diatomaceous earth directly. It was found that many of the bedbugs that had not been allowed to contact the diatomaceous earth directly died shortly after contacting the bedbug that did contact the diatomaceous earth directly. Also, the fluorescent dye was observed on the bedbugs that died shortly after contacting the bedbug that did contact the diatomaceous earth directly, suggesting that such bedbugs came into contact with diatomaceous earth by contacting the bedbug that had contacted the diatomaceous earth directly. Therefore, it is believed that causing one bedbug to contacted diatomaceous earth directly may in some cases cause the deaths of several bedbugs.

In another experiment on Feb. 18, 2012, mortality of CELATOM™ MN-51 was compared with two commercially available insecticides, namely the insecticides known as ALPINE DUST™ and MOTHER EARTH™. The various products were weighed on a small filter paper, which was then placed in a Petri dish (about 5.0 cm or about 2 inches diameter). Bedbugs were introduced in the various Petri dishes, and mortality was assessed in each of the Petri dishes after 24 hours and after 48 hours. Four concentrations of each product were used, the concentrations ranging from 0.25 mg to 4 mg, and there were three replications of between 9 and 11 bedbugs in each replication. A probit analysis was used to calculate LC₅₀ and LC₉₅ (lowest lethal concentrations sufficient to kill 95% of the bedbugs) values and confidence intervals (“CIs”) for the LC₅₀ and LC₉₅ values, as shown in Table 6 below.

TABLE 6 LC₅₀, LC₉₅, and CI for CELATOM ™ MN-51, ALPINE DUST ™, and MOTHER EARTH ™. Product Time (hours) LC₅₀ CI of LC₅₀ LC₉₅ CI of LC₉₅ CELATOM ™ 24 0.24 0.14-0.32 0.95 0.69-1.98 MN-51 ALPINE 24 6.36  3.83-29.27 52.57 15.88-3366  DUST ™ ALPINE 48 1.72 1.37-2.18 6.6  4.47-13.44 DUST ™ MOTHER 24 0.26 0.14-0.36 1.37 0.91-3.44 EARTH ™

The data in Table 6 show that CELATOM™ MN-51 required lower concentrations (specifically lower LC₅₀ and LC₉₅, and lower CIs for those values) than ALPINE DUST™ and MOTHER EARTH™ in that experiment, and therefore it is believed that CELATOM™ MN-51 may generally be more effective than ALPINE DUST™ and MOTHER EARTH™ in controlling populations of bedbugs.

In general, it is believed that diatomaceous earth may damage exoskeletons of animals having exoskeletons, which damage may lead to dehydration and death of the animals. Therefore, it is believed that diatomaceous earth, and various apparatuses, kits, and systems such as those including diatomaceous earth as described herein, may be effective in the control of populations of one or more of animals having exoskeletons, arthropods, arachnids, insects, and bedbugs. Herein, “control” of an animal population may include prevention of growth or survival of such a population before discovery of the population, and also killing one or more members of such a population after discovery of the population. Diatomaceous earth is also a natural product, and in general, natural products may be preferable over other pest control products because natural products may be less harmful to humans or more generally to the environment. Animals that may desirably be killed by diatomaceous earth also include cockroaches, ants, fleas, and other pests.

Although CELATOM™ MN-51 and CELATOM™ MN-53 and other products have been discussed above, some embodiments may include other types of diatomaceous earth, which may be supplied by other suppliers. In general, such diatomaceous earth in some embodiments may be heat-treated or flash dried diatomaceous earth, such as diatomaceous earth flash dried at about 480° C. for about 15 seconds for example, or may more generally be modified diatomaceous earth. More generally, such diatomaceous earth may have one or more properties similar to one or more of the properties of CELATOM™ MN-51 or CELATOM™ MN-53 listed in Tables 1 and 2 above in order to achieve effects that may be similar to the effects of CELATOM™ MN-51 or CELATOM™ MN-53 described above.

Further, other embodiments may include products other than diatomaceous earth that may be effective to control bedbug populations or more generally as an insecticide or pesticide. For example, U.S. Pat. No. 8,101,408 describes various legume extracts, such as one or more of PA1b-related peptides, terpenoid saponins, triterpenoid saponin, soyasaponin I, soyasaponin II, soyasaponin III, soyasaponin VI, dehydrosoyasaponin I, echinocystic acid 3-glucoside, glycyrrhizic acid, hederacoside C, beta-escin, alpha-hederin, and other acetic acid precipitated insecticidal components. In various embodiments, one or both of diatomaceous earth and such legume extracts may be incorporated into thermoplastic bodies, for example by adding the diatomaceous earth, the legume extracts, or both to the thermoplastic material of the body when the thermoplastic material is in a liquid phase and before the thermoplastic material is injected into a mold.

Still referring to FIG. 11, the decorative cover 102 and the body 106 may be manufactured to have the hook-and-loop connectors 138 and 154 in predetermined positions on the decorative cover 102 and on the body 106 respectively, and such predetermined positions may be determined to impart a desired position and tension of the decorative cover 102 over the padding 104. Therefore, the decorative cover 102 may be installed with such a desired position and tension simply by aligning the connector 138 with the connector 154. Therefore, in the embodiment shown, the connector 154 on the body 106 complementary to the connector 138 on the decorative cover 102 may simplify holding the decorative cover 102 on the body 106 because a desirable position of decorative cover 102 on the body 106 may be predetermined by the respective positions of the complementary connectors 138 and 154, which may eliminate a need to position a decorative cover carefully on a frame while connecting the decorative cover to the frame. Further, in some embodiments, there is no need to stretch or deform the decorative cover 102 when installing it on the body 106.

Still further, in the embodiment shown, the connectors 138 and 154 are continuous hook-and-loop connectors, and therefore may avoid unsightly looks that can result from connecting a decorative cover only at discrete points on a frame.

Referring to FIG. 12, another illustrative body is shown generally at 300 and has a front side shown generally at 302 and having a front surface 304. The front surface 304 includes a generally flat planar portion 306 and an inward-facing portion 308. The body 300 also has a rear side shown generally at 310 opposite the front side 302, and an outwardly facing lateral surface 312. The inward facing portion 308 of the front surface 304 is therefore between the generally flat planar portion 306 and the lateral surface 312 of the body 300. The body 300 is substantially similar to the body 106 discussed above, may similarly function as an apparatus for holding a decorative cover, and may include similar materials to the body 106, although the inward-facing portion 308 includes a first portion 314 adjacent and extending generally perpendicular to the generally flat planar portion 306, a second portion 316 adjacent the first portion 314 and extending non-parallel to the first portion 314 and away from the generally flat planar portion 306, and a third portion 318 adjacent the second portion 316 and extending generally parallel to the first portion 314 and away from the generally flat planar portion 306. Also, the lateral surface 312 in the embodiment shown includes a complementary portion 320 that is generally complementary to the inward-facing portion 308.

Therefore, referring to FIG. 13, the body 300 is stackable against an adjacent similar body 322 on the front side 302 of the body 300, and against an adjacent similar body 324 on the rear side 310 of the body 300. Thus, the complementary portion 320 of the lateral surface 312 of the adjacent similar body 322 contacts the inward-facing portion 308 of the body 300 when the adjacent similar body 322 is stacked against the front side 302 of the body 300. Further, the complementary portion 320 of the lateral surface 312 of the body 300 contacts the inward-facing portion 308 of the adjacent similar body 324 when the adjacent similar body 324 is stacked against the rear side 310 of the body 300.

Referring to FIGS. 14, 15, and 16, another illustrative body is shown generally at 326 and includes a front side shown generally at 328 and an opposite rear side shown generally at 330. The front side 328 has a front surface 332 having a perimeter 334, and includes a generally flat planar portion 336 and an inward-facing portion 338. The body 326 also includes an outwardly facing lateral surface 340 between the front surface 332 and a rear surface 342 on the rear side 330. The body 326 defines a plurality of through-openings such as illustrative through-openings 344 and 346 for receiving respective fasteners as discussed above with the through-opening 172 shown in FIG. 6, for example. The through-openings such as the through-opening 344 and 346 also have respective cleats 348 and 350 that are substantially the same as the cleat 182 discussed above and shown in FIG. 6. On the rear side 330, the body 326 defines projections 352, 354, and 356 having respective through-openings shown generally at 358, 360, and 362 for receiving respective projections 364, 366, and 368 of a wall-mountable cleat 370 that is substantially the same as the cleat 108 discussed above. The body 326 also defines, on the rear side 330, projections 372, 374, and 376 having respective through-openings shown generally at 378, 380, and 382 for receiving the projections 368, 366, and 364 respectively of the cleat 370. The body 326 is thus wall-mountable in a first orientation when the projections 364, 366, and 368 are received in the through-openings 358, 360, and 362 respectively, and in a second orientation perpendicular to the first orientation when the projections 364, 366, and 368 are received in the through-openings 382, 380, and 378 respectively. The spaced apart edges of the projections 364, 366, and 368 thus function as a connector, the spaced apart edges of the projections 356, 354, and 352 thus function as a connector complementary to the spaced apart edges of the projections 364, 366, and 368, and the spaced apart edges of the projections 376, 374, and 372 also function as a connector complementary to the spaced apart edges of the projections 364, 366, and 368.

The body 326 also has a connector 384 continuously adjacent the perimeter 334 of the front surface 332, and in the embodiment shown the connector 384 is on the lateral surface 340. The connector 384 is complementary to a connector such as the connector 138 on the decorative cover 102 shown in FIG. 3, and thus the body 326 also functions as an apparatus for holding a decorative cover.

The body 326 also defines additional through-openings such as illustrative through-openings 386 and 388, which may reduce a weight and manufacturing cost of the body 326. In the embodiment shown, the additional through-openings such as the through-openings 386 and 388 are generally rectangular and separated by generally linear members such as illustrative generally linear members 390 and 392, which have through-openings such as the through-openings 344 and 346 and cleats such as the cleats 348 and 350. However, in alternative embodiments, the through-openings such as the through-openings 386 and 388 may be omitted or closed by thin films of thermoplastic material (not shown) received against the front surface 332.

The body 326 also has clips such as illustrative clips 394 and 396, and such clips function as a light source connector for holding a light source (not shown), which may include a plurality of LED lights in a light string, for example. The clips such as the clips 394 and 396 are substantially the same as the clips such as the clips 264 and 266 shown in FIGS. 5 and 7 and discussed above.

Also, on the rear side 330, the body 326 defines a storage compartment 398 for storing objects. In the embodiment shown, the storage compartment 398 includes a removable cover 400. Again, in some embodiments, the storage compartment 398 may hold one or more of buttons, a needle, and thread to impart a textured appearance to the outer surface 112 of the decorative cover 102 as described above, for example.

The body 326 also includes additional projections 402, 406, 408, and 410 on the rear surface 342 to contact at least a portion of an adjacent similar apparatus when the adjacent similar apparatus is stacked against the rear side 330 of the body 326. The additional projections 402, 406, 408, and 410 in some embodiments may thus impart greater stability to a system of stacked similar bodies. The body 326, and other bodies and cleats such as those disclosed herein, may be made from materials such as those discussed above for the body 106.

Referring to FIG. 25, another illustrative embodiment is shown generally at 474 and is similar to the body 326 shown in FIGS. 14, 15, and 16, except that on a rear side 476 of the body 474, the body 474 defines receptacles 478, 480, 482, and 484. In the embodiment shown, the receptacles 478 and 480 receive a support 486, and the receptacles 482 and 484 receive a support 488. When the support 486 is received fully in the receptacles 478 and 480, an exposed end shown generally at 490 of the support 486 has a plurality of through-openings 492 for receiving fasteners (not shown) to attach the support 490 to a bed frame (not shown). Likewise, when the support 488 is fully received in the receptacles 482 and 484, an exposed end shown generally at 494 of the support 488 defines a plurality of through-openings 496 for receiving fasteners (not shown) for attaching the support 488 to the bed frame (not shown). The receptacles 478, 480, 482, and 484 thus function as a connector for connecting the body 474 to a bed frame.

Referring to FIGS. 17, 18, and 19, another illustrative body is shown generally at 412 and is similar to the body 326 except that on a rear side 414 of the body 412, the body 412 includes a plurality of structural reinforcing ribs such as illustrative structural reinforcing ribs 416 and 418.

The body 412 in the embodiment shown is substantially thermoplastic and may be formed in a mold. Such molds are costly to produce, and therefore such molds are preferably adjustable in size to produce bodies similar to the body 412 but having different dimensions. For example, referring to FIG. 17, the line 420 divides the body 412 into portions 422 and 424 that may be formed by respective separate portions of a mold. Those portions of the mold may be separated, and an additional portion of the mold may be inserted therebetween to form a body similar to the body 412 but larger by having an additional portion (not shown) between the portions 422 and 424.

In the embodiment shown, the body 412 has a height 426 of about 109.2 cm (or about 43 inches), and a width 428 of about 147.3 cm (or about 58 inches). Such dimensions may be suitable for a headboard for a North American double-sized bed having a width of about 137.2 cm (or about 54 inches). However, in North America, a queen-sized bed having a width of about 152 cm (or about 60 inches) is also common, and therefore a body suitable for use as a headboard for a North American queen-sized bed may have a width of about 162.6 cm (or about 64 inches) by expanding the mold by inserting a mold expansion portion into the mold, the mold expansion portion having a width of about 15.3 cm (or about 6 inches) to cause an additional portion having a width of about 15.3 cm (or about 6 inches) to be formed in the body 412 between the portions 422 and 424. Also, some North American king-size beds have a width of about 203.2 cm (or about 80 inches), and therefore two bodies 412 may be rotated by 90° and positioned adjacent each other to have a common width of about 218.4 cm (or about 86 inches, namely about twice the height 426) and to have a common height of about 147.3 cm (or about 58 inches, namely about equal to the width 428). Therefore, with a mold expansion portion to form an additional portion between the portions 422 and 424, a single mold may produce bodies suitable for headboards of three different sizes of beds, such as North American double-, queen-, and king-sized beds for example.

In alternative embodiments, a body may include telescoping portions to permit adjustment of an overall size of the body.

Referring to FIG. 20, another illustrative body is shown generally at 430 and is similar to the body 412 except that the body 430 includes additional generally linear members 432 and 434 for additional structural strength. The body 430 also may function as an apparatus for holding a decorative cover similar to the bodies 106, 300, 326, and 412, and may include similar materials as described above.

Referring to FIG. 21, another illustrative body is shown generally at 436. The body 436 may function as an apparatus for holding a decorative cover similar to the bodies 106, 300, 326, 412, and 430, and may include similar materials as described above. The body 436 has a rear side shown generally at 438 and having a rear surface 440. The body 436 defines through-openings generally at 442, 444, and 446 for receiving fasteners similar to the through-opening 172 discussed above and shown in FIG. 6, for example.

The body 436 also defines through-openings 448 and 450. The through-opening 448 is adjacent a bevelled edge 452, and the through-opening 450 is adjacent a bevelled edge 454. The bevelled edges 452 and 454 are connectors complementary to a French cleat to mount the body 436 on a wall (such as the wall 88 shown in FIG. 1).

Referring to FIG. 22, an illustrative French cleat is shown generally at 456 and includes a bevelled edge 458 for contacting one of the bevelled edges 452 and 454 on the body 436 shown in FIG. 21. The bevelled edge 458 of the French cleat 456 thus also functions as a connector. The French cleat 456 also has through-openings shown generally at 460 and 462 for receiving fasteners (not shown) for mounting the French cleat 456 on a wall (such as the wall 88 shown in FIG. 1). The French cleat 456 is thus wall-mountable. The French cleat 456 also includes an inclination measuring device 464, which in the embodiment shown is a bubble level to facilitate mounting the French cleat 456 on a wall (such as the wall 88 shown in FIG. 1) such that the bevelled edge 458 is level.

Referring to FIG. 23, the body 436 is shown with the bevelled edge 454 of the body 436 nearly in contact with the bevelled edge 458 of the French cleat 456. When the body 436 is lowered relative to the French cleat 456 such that the bevelled edge 454 of the body 436 contacts the bevelled edge 458 of the French cleat 456, the body 436 is supported by the French cleat 456 and thus mounted on the wall. In the embodiment shown, the bevelled edge 454 is longer than the bevelled edge 458, and therefore the body 436 in some embodiments can be moved relative to the French cleat 456 to position the body 436 in a desired position, such as at the head of a bed, for example.

Referring to FIG. 24, an adjacent similar body 466 is stackable against a front side 468 of the body 436, and a similar adjacent body 470 is stackable against the rear side 438 of the body 436.

The embodiments described above are substantially rectangular, but one skilled in the art will appreciate that other embodiments may have non-rectangular shapes. As illustrative examples, FIG. 26 illustrates a headboard 498 having a shape that may be referred to as an “arched” shape, FIG. 27 illustrates a headboard 500 having a shape that may be referred to as a “camel back” shape, and FIG. 28 illustrates a headboard 502 having a generally rectangular shape with rounded upper corners. It will be appreciated that embodiments such as those illustrated in FIGS. 2 to 25 may alternatively have shapes such as those illustrated in FIGS. 26 to 28, for example.

As indicated above, the bodies disclosed above may form part of headboard systems that hold decorative covers without requiring conventional upholstery techniques and without requiring other more cumbersome alternatives to upholstery. Further, the bodies discussed above may be used to hold decorative covers for applications other than headboards, such as decorating walls more generally, for example. Still further, the bodies discussed above may be stacked as shown in the drawings, for example, and such stacking may permit compact and cost-effective shipping while the contact between adjacent similar bodies stabilizes the bodies during shipping, which may reduce damage during shipping that may be caused from relative movement of adjacent bodies. Further, light sources such as those disclosed above may enhance the visual appearance of walls to which the bodies disclosed above are mounted.

Referring back to FIG. 1, the nightstand 92 includes legs 504, 506, 508, and 510 for contacting the floor 86. The nightstand 92 also includes a generally rectangular frame 512 supported by the legs 504, 506, 508, and 510 over the floor 86, and the nightstand 92 also includes a drawer 514 slidably receivable in the generally rectangular frame 512. In various embodiments, one or more of the legs 504, 506, 508, and 510, the generally rectangular frame 512, and the drawer 514 are substantially thermoplastic bodies of the nightstand, which is a furniture apparatus. One or more of such substantially thermoplastic bodies may be formed in a mold, and in some embodiments, carbon plastic may be desirable because of durability, a polished finish, and various colours that may be available with carbon plastic.

Still further, one or more of such substantially thermoplastic bodies may include incorporated therein one or more of the diatomaceous earth products and legume extracts discussed above. As with the other embodiments discussed, above, such diatomaceous earth, legume extracts, or both may be incorporated into such substantially thermoplastic bodies by adding the diatomaceous earth, the legume extracts, or both to the thermoplastic material when the thermoplastic material is in a liquid phase before the thermoplastic material is injected into a mold. In one embodiment, about 30% by weight of such substantially thermoplastic bodies may be diatomaceous earth or a mixture of diatomaceous earth and one or more legume extracts. Further, additional diatomaceous earth, legume extracts, or both may be adhered to inner surfaces of such substantially thermoplastic bodies, such as inner surfaces of the generally rectangular frame 512 or the drawer 514 for example, for further exposure of the diatomaceous earth to animals such as bedbugs.

In alternative embodiments, the generally rectangular frame 512 and the drawer 514 may be replaced by a table surface platform supported by legs similar to the legs 504, 506, 508, and 510. According to such an embodiment, a furniture apparatus may include a table including substantially thermoplastic bodies and one or both of diatomaceous earth and legume extracts as described above.

Still referring to FIG. 1, the dresser 94 includes a generally rectangular frame 516 and a plurality of drawers, such as the drawers 518 and 520, slidably receivable in the generally rectangular frame 516. The generally rectangular frame 516 and the plurality of drawers slidably receivable therein may be substantially the same as the generally rectangular frame 512 and the drawer 514 described above.

The bed 96 includes a generally rectangular platform 522 for supporting the mattress 98. The bed 96 also includes four substantially thermoplastic bodies at respective corners of the generally rectangular platform 522, and such substantially thermoplastic bodies 524, 526, and 528 are shown in FIG. 1. Such substantially thermoplastic bodies in the embodiment shown are generally cylindrical, and act as supports for contacting the floor 86 and for supporting the generally rectangular platform 522 and thus the mattress 98 above the floor 86. In alternative embodiments, the bed 96 may include more or fewer substantially thermoplastic bodies acting as such supports.

As indicated above, in some embodiments, carbon plastic may be a desirable material for some furniture apparatuses because carbon plastic may be coloured with a desired colour, and externally visible surfaces of the carbon plastic may be polished to reveal the desired colour with a durable and attractive polished finish. Further, in some embodiments, one or more internal surfaces (such as internal surfaces of the generally rectangular frames 512 and 516 shown in FIG. 1, for example, which may be visible when drawers are removed from the generally rectangular frames but otherwise visibly concealed by the drawers) may be darkly coloured, such as coloured black or another dark colour. Thus, when diatomaceous earth, for example, is applied to such internal surfaces, the lighter colour of the diatomaceous earth may make the diatomaceous earth more easily visible on such surfaces, and may facilitate noticing an absence of such products on such surfaces. Therefore, such darkly coloured internal surfaces in some embodiments may assist with visibly determining whether such internal surfaces have been sprayed or otherwise treated with diatomaceous earth or another more lightly coloured product, and such visual determinations may facilitate determining where and when such diatomaceous earth or other products should be applied to ensure a desired amount of such diatomaceous earth or other products on various furniture apparatuses.

Although the nightstand 92, the dresser 94, the bed 96, the mattress 98, and the headboard system 100 are described above, various furniture apparatuses, kits, and systems according to alternative embodiments may include one or more substantially thermoplastic bodies including diatomaceous earth, legume extracts, or both incorporated therein, and such furniture apparatuses according to some embodiments may assist in the control of bedbug and other animal populations. Therefore, commercial use of such apparatuses, kits, and systems may involve distributing, selling, offering for sale, or placing such apparatuses, kits, and systems in bedrooms or hotel rooms in an effort to control populations of animals, such as animals having exoskeletons, arthropods, arachnids, insects, and Cimex lectularius for example, in such bedrooms or hotel rooms.

Further, it is believed that bedbugs are often introduced into a bedroom or hotel room from occupants of the bedroom or hotel room, or from the belongings of the occupants of the bedroom or hotel room. It is also believed that such occupants and belongings are likely to be on one or more of a bed, nightstand, and dresser in the bedroom or hotel room, and therefore that bedbugs are likely to be introduced into the bedroom or hotel room in one or more of a bed, nightstand, and dresser in the bedroom or hotel room. It is also believed that bedbugs are likely to dwell in a bed in the bedroom or hotel room. Therefore, in some embodiments, the nightstand 92, the dresser 94, the bed 96, and the headboard system 100 may cooperate with each other and collectively facilitate control of bedbugs by controlling bedbugs in particular locations where bedbugs may be introduced or may likely dwell into the bedroom or hotel room.
